The I2C Level Converter allows you the run 3.3v logic sensors like the Bar30 or Celsius and other accessories off of a 5v logic device like the Arduino Uno!
A selectable solder jumper lets you run 5v or 3.3v power to your sensor, independent of the 3.3v I2C logic. Built in four pin DF13, Dronecode Mini standard JST-GH, and 0.1″ header pin connectors provide maximum flexibility and ease of use.

1. Determine if your device is 3.3v or 5v powered and set solder jumper for correct output. (Note, most I2 devices are 3.3v, but the Bar30 and Celsius operate best with 5v power.)
2. Plug your device into one of the input ports (4 pin 0.1” header, JST-GH, DF13) and your 5v device to the host device output port.
3. That’s it! You’re ready to communicate between the devices.
